Abstract
A method of operating a top submerged lance furnace, and more particularly but not exclusively to a method of coating an end of a lance of a top submerged lance furnace with a slag layer, as well as a method of maintaining a uniform heat distribution about the periphery of the lance of the top submerged lance furnace. In terms of the method, the lance is caused to rotate, and a fluid is passed through the lance before it is inserted into the molten material bath inside the crucible.
